->x; } } ?> So you can create objects in the following ways: $obj =new Something (6); The constructor automatically assigns a value of 5 to the member variable x, the constructor and member functions are normal PHP functions, so you can use the default parameters. function Something ($x = "3", $y = "5") And then: $obj =new Something (); X=3 and Y=5 $obj =new Something (8); X=8 and Y=5 $obj =new Something (8,9); X=8 and Y=9 The default parameter is defined in the same way as

object x. Polymorphism is naturally supported in PHP (think about this situation in the C ++ compiler if it is compiled, that method is called? However, you don't know what the object type is. Of course this is not the case now ). Fortunately, PHP supports polymorphism. Function niceDrawing ($ x ){ // Supose this is a method of the class Board. $ X-> draw ();

PHP object-oriented programming (oop) learning notes (5)-PHP namespace. Namespace overview in PHP, namespace is used to solve two problems encountered when you create reusable code such as classes or functions when writing class libraries or applications: user-written code and P Namespace overview In PHP, the namespace is used to solve the two problems encounter

. Polymorphism is naturally supported in PHP (think about this situation in the C ++ compiler if it is compiled, that method is called? However, you don't know what the object type is.

Throw Overflow (); 22 23 V [Top] = C; 24 Top ++ ; 25 } 26 27 STACK: Pop () 28 { 29 If (Top = 0 ) 30 Throw Underflow (); 31 Top -- ; 32 Return V [Top]; 33 } From the above, we can see how to define a class. This is just a type of stack. Different types of stacks may have different implementation methods of push and pop, in this way, we can use the object-

For each function called by the program, the assembly to this function is included directly in the executable, allowing Fu Ction calls to directly address code. Dynamic.
